'To all wlwm it may concern: f v

Be it known that I', CLYDE-S. PEL'roN', a citizen of the United States, ,residin at Akron, in the county of Summit'and tatc of Ohio, have invented a new and useful Automobile-Heater, of which the following is pecification. p I 1 This invention relates to heaters for automobiles in which the heating medium is the exhaust of the engine,and it is the objectof the invention to provide aheaterof this kind which can be readily installed in the car without modifying the.structurejthereof, or changing the arrangement of the exhaust pipe of the engine. 1 v

A further objectofthe inventionis'to provide a radiator which, vhileibeingof great heating efficiency, will operate on "the" principle of a muiller to render thedischair'ge of the gases from-the motor'substantial y] noiseless.- These objects are obtained by alconihi'nfa tion and arrangement of parts to'befhercin after described and claimed, thesam evbe illustrated in the accompanying drai(rings;-v in which drawings, Figure 1 is a plan view of the'rifdiator. Fig. 2 is a-horizontal sectionthereof Fig. 3 is a transverse section on the lined-,3 of; Fig. 1. Fig.4 is an end ,view of'theiindif, ator. Fig. 5 is a sectional view of the valve. to be hereinafter described. F 6 is an.

showing a slightly modified form of-radiator structure.

An' outlet 5 is connected to each group. The gas is conducted from the pipes -1, in a practlcally continuous flow, without noise." Both groups of pipes or conduits 1 communicate with-theoutlet pi Je or manifold 6. In-reaching the point in t 1e manifold 6 to which the outlet incarcr the discharge endof said manifold is connected, the gas discharged, into the pipes -Li's broken e ing a difi'ereht distance in reaching-7 said point than any other stream, with the result that the impulses from, the engine irreconyerted lI1i0 Il practically continuousstream einboiliinent i of; my invention shown .strcauis- .inithc".body of the heater and dil iirtherniore, the'j gas discharged: into the heater is greatly expanded, n 'tllQ cmbodi heater andthe conversion of the impulses m'to, a contmuousstream flowin through In the side walls of the casing are air conduits 7 which, register at their upper' erforations 8- in thejplatefi, and open into; iecasing nearits bottom.

At 10 is indicated the exhaust pipe or i mane ofthe engine; At any convenient point,'an' opening 11 isrmade in this pipe, over which openingis placed avalye cas ng 12. This casmg'is a shell fittin'g that portion of; the exhaust pipe in which, the Op ning;

outstandin flanges 1 10 11 is made, and'h'a' 13 at its ends. The she 1 extends o y partly aronndthe exhaust pipe, and theremaining portion of said pipe is encircled. by two clamping members 14 shaped to fit said portion of the pipe, and having outstand, ing flanges 15 at their ends. Tiese flan ch 15 are located opposite the flanges 13. Be ts 16 passing through registerin openings the flanges 13 and 16 securey fasten the valve casing to the exhaust pipe. By conpoint on the exhaust lindrical chamber pass rofllers 27 mounted on studs a segmental gear 30 mounted for rota structing't valve casing,,and mounting the same on the exhaust pipe as herein Ilescrihed, said casing can be applied at an? pipe, the opening 1 being made at the point where the valve is to be located, and it is not necessary to resort to expensive pipe cutting, threading or brazin The val vecasing is provided with a cy- 17 in which works a retary valve 18 carried on a shaft 19 mounted for rotar movement in the end walls of the chem er, and projecting therefrom. To one of the; projecting. ends of the shaft is made fast an arm 20 for-rocking said shaft, whereby the valve is operated. The valve is so constructed and located as to extend across an opening in the, chamber 17 communicating with the interior 0f the exhaust pipe through ,the opening 11, ma; u on swinging t e valve awayjfro'zn the rst mentioned opening, the interior off-the chamber lf is placed in communication with" the interior .of the exhaust pipe andthe exhaust a'ses are the'p permittedito pass into said chamber', from'which they 'pass into 9. pi e 21 connected to the pipe 4. On the cham er 17 is a ni le 22't'owhich the pipe 21 is connected. Fl he valve has a se mental shape, and when open it exten s partly into the exhaust pipe, and deflects a portion of the'exhaust gas into the chainer 17 V The'lplate 3 projects a short distance beyond t aside and end walls of the casing 2, and in the (prog'ecting portion of the plate at on an o the, casin is a vertical slot 23 in which works a u 24 rising from a yoke 25 monntedfor sli in movement on the corresponding end wal of the casing. The yoke straddles the pipe 4, and has guide slots 26 at its ends thr 'ugh which i 28 carried 1y and projectmgfroni'the end wall. of the casing. The yoke is free to slide back and forth to the extent of the length of the slots 26. The lower edge of t; e yoke is formed into a rack 29 which is in mesh with movement on a stud wall of the. casing. from the segmental by a link 33 to th shaft 19. a

The yoke 25, and its associate parts herein 31 carried by the en -An arm '32 projects gear, and is connected arm 20 of'the valve described, are provided for o erating the valve 18, which is'done by Slit ing the yoke back and forth on its support. The lug 24 projectga suflicient distance from the todp of the )late 3 so that it may been age by the ioot or hand to, operate, the yo e. The sliding movement of the yoke, through the rack 29, swings the segmental gear 30 on the stud 31,and through the arm 32, link 33, and arm 20, rocks' the shaft 19 and operates the valve 18. The extent to which the valve is opened governs the volume ofthe exhaust gases flowing into, the pipes 1, and the degree of heat desired is therefore readily regulated by opening or closing the valve more or less. If it IS desired to shut off the heat altogether, the valve will be entirel closed, whereupon the exhaust is cut oil from the radiator, and passes directly to the muffler of the exhaust pipe 10. In use, the radiator will be mounted in an openin made in the floor or wall of that portion 0 plate 3 extending flush with said floor or wall. It will not be necessary to alter or modify the structure of the car, the only change required being to make the opening to receive the radiator, and to pply the valve to the exhaust pipe at any convenient point thereon.

Although the invention is designed primarily for automobiles propelled by internal combustion engines, to stedzn plied for or hot gases are avai able.

' Fig. 7 shows a sli htly-modified form of r'adiator structure, t e same being designed to obtain a greater eiiiciency and also to makea more practicable construction. A series "of copper tubes 34 extend between, and are connected at their ends to manifolds35 and 36 respectively, the former beit may also be applied lpropelled vehicles, and also apeating purposes wherever steam ing the inlet and the latter the outlet. Each manifold may manifold 35 has two branches, to each of which a group of tubes 34 is connected, so

that the incoming gas is divided into two streams,- one passing into one group of tubes, and the other into the other group. The outlet manifold 36 has an outlet for each group of tubes.

The connection between the valve and the radiator maybe made by flexible pipes or tubes in order that the radiator may be readily moved and its location changed if desired.

What is claimed is: a 1. The combination, with an engine exhaust pipe, of a. radiator comprising a plube exist in a single piece. The

rality of radiator units communicating with the exhaust ipe, an outlet pipe common to said. units, t e radiator units bei so arranged as to provide a-series of' acts of varying length interposed between the radiator inlet and outlet, whereby the impulses from the engine are, broken up and dis- 'with the exhaust pipe,

charged in a substantially continuous stream through the outlet. i

2-. The combination, with an engine ex-- haust 'pipe having a valve, of a radiator eonnected' to said pipe through said valve, said radiator comprising a plurality of radiator units communicating at one end an outlet pipe common to the discharge ends of said units, the combined cross-sectional area of said units being greater than that of the radiator inlet and the said units being so arranged as to provide ducts of varying length interposed between the radiator inlet and outlet, whereby the impulses from the engine are broken up, expanded, and discharged in a substantially constant stream through the radiator outlet.

:5. The combination, with an engine exhanst pipe, of a radiator comprising a plurality of groups of radiator units with an inlet common to said groups and communicating with the exhaust pipe, an outlet header connnu'nicating with the discharge ends of said groups, the radiator units being so arranged as to provide a series of ducts of varying length between the. inlet and the discharge outlet, whereby tlfe inipulses from the engine are broken up and dis-charged in a substantially constant stream through-the outlet.

In testimony that I claim the foregoing as in) own, I have hereto aflixed my signature inthe presence of two witnesses.
